CVE-2023-0746Network attack vector

Browser script execution via unneutralized help-page URI

Published Mar 10, 2023 · Updated Feb 27, 2025

Reflected XSS in the help page of Gigamon GigaVUE-FM with GigaVUE-OS 5.0.202 allows remote attackers to execute script via a crafted URI. The unauthenticated help page incorporates attacker-controlled URI content into its response without neutralizing JavaScript. Exploitation requires a user to follow or submit the crafted URI, after which the script runs in the page's browser context and can read or alter data available there.
